"Background: The purpose of this study was to provide a reference of chronic diabetes complications by investigatingthe prolonged hyperglycemia effects on hematological, biochemical and histopathological changes (liver, kidney,spleen, cardiac muscle, adrenal gland, and endocrine pancreas) in diabetic rats induced by streptozotocin. Methods:Ten adult female Sprague-Dawley of uniform age were divided into two Groups. Group 1 was made diabetic by singleintraperitoneal injection of streptozotocin (60 mg/kg/bw) whereas Group 2 served as control. After six months, the ratswere anesthetized using pentobarbital. Cardiac puncture was performed to get 3 ml of the blood sample; following 12hours of an overnight fast. Serum chemistry test and complete blood analysis for lipid profile and blood glucose test;liver and renal functions were performed. Tissue specimens of liver, kidney, spleen, cardiac muscle, adrenal gland, andendocrine pancreas were fixed in 10% formal saline and processed for histological study. Results: There were severehistopathological changes in the affected organs; and the presence of a significant abnormality of lipid profile, liver, andrenal functions. Conclusions: The presence of histopathological changes with abnormal biochemical changes is relatedto the chronic absence of insulin production in the destroyed β –cells which reflect the diabetic complications in ahuman being."

Introduction: Papillary thyroid carcinoma (PTC) is one of the most common forms of malignant thyroid in the world. In Indonesia, it is found that out of all thyroid malignancies, PTC accounts for 83% of all the cases as well as accounting 61% of all thyroid nodule cases. Broadly though, the etiology of most cases remains unknown and does not have a specific etiology. The clinicopathological characteristics of PTC consists of age, sex, tumor size, lymphovascular invasion, soft tissue invasion, and variant of the PTC. Lymph node metastasis (LNM) may also occur in some cases of PTC, with research showing that 50-60% of LNM cases occurring. Patients with PTC and LNM have also shown to have a worse prognosis compared to their counterparts without LNM. This study aims to find the clinicopathological profile of PTC and its association with the LNM. Methods: This research is a descriptive analytical research using a retrospective method using secondary data from medical records and patient archives from the Department of Anatomical Pathology FKUI-RSCM that had been diagnosed with PTC from a period of January 2014 to December 2018. Results: This study found that there are differences between aggressive and non-aggressive variants in the occurrence of LNM (p =0.001). In addition, the sex of the patient and tumor size showed statistically significant differences for LNM occurrences in PTC (p = 0.001 and p=0.026, respectively). Furthermore, soft tissue invasions showed statistically significant differences of LNM occurrences in PTC (p = 0.001). This study also found that there were no significant differences of age or lymphovascular invasion in the occurrence of LNM in cases of PTC. Conclusion: The study shows that the sex, variant, tumor size, and presence soft tissue invasion in patients with PTC are associated with the increased risk of LNM occurrence. Future research may use prospective longitudinal studies to better keep track of essential data from patients."

"Latar Belakang: Karsinoma sel skuamosa rongga mulut (KSSRM) adalah salah satu kanker yang sering ditemui di Indonesia, dengan faktor risiko meliputi merokok, konsumsi alkohol, infeksi virus, faktor konsumsi, lokasi tumor, jenis kelamin, dan usia. Pemeriksaan histopatologis dengan pewarnaan hematoksilin dan eosin (H&E) merupakan metode utama untuk diagnosis definitif KSSRM. Akurasi diagnosis dan penilaian derajat diferensiasi tumor sangat penting dalam menentukan diagnosis dan pilihan penatalaksanaan. Selain derajat diferensiasi, analisis lebih lanjut terhadap pola invasi dan adanya invasi limfatik, vena, serta saraf diperlukan untuk memperoleh penilaian yang lebih objektif. Pola invasi, invasi limfatik, invasi vena, dan invasi saraf memberikan informasi lebih mendalam mengenai agresivitas dan potensi penyebaran tumor, sehingga analisis invasi ini lebih penting dibandingkan hanya menilai derajat diferensiasi tumor seperti pada prosedur standar. Metode: Penelitian deskriptif analitik menggunakan sampel jaringan KSSRM yang diberi pewarnaan H&E dan diamati menggunakan mikroskop cahaya. Hasil: Mayoritas kasus KSSRM ditemukan di lidah (61,5%), dengan pasien perempuan (56,4%) dan kelompok usia >55 tahun (53,8%). Pola invasi agresif (pulau satelit, invasi limfatik signifikan (++), invasi vena signifikan (++), dan invasi saraf signifikan (++) memiliki hubungan signifikan dengan derajat diferensiasi buruk (p<0,05). Kesimpulan: Tidak ada hubungan signifikan antara lokasi tumor, jenis kelamin, dan usia dengan derajat diferensiasi KSSRM. Ditemukan hubungan antara pola invasi, invasi limfatik, invasi vena, dan invasi saraf dengan derajat diferensiasi pada pasien KSSRM. Semakin agresif pola invasi, maka semakin buruk derajat diferensiasi KSSRM. Semkain buruk derajat diferensiasi, maka semakin tinggi tingkat invasi limfatik, vena, dan saraf KSSRM.

Background: Oral squamous cell carcinoma (OSCC) is a prevalent type of cancer in Indonesia, with risk factors including smoking, alcohol consumption, viral infections, dietary factors, tumor location, gender, and age. Histopathological examination using hematoxylin and eosin (H&E) staining is the primary method for the definitive diagnosis of OSCC. Accurate diagnosis and tumor differentiation assessment are crucial in determining diagnosis and treatment options. In addition to the degree of differentiation, further analysis of invasion patterns, as well as lymphatic, venous, and neural invasion, is essential for a more objective evaluation. These invasion factors provide deeper insight into the aggressiveness and potential spread of the tumor, making their analysis more critical than solely evaluating tumor differentiation as in standard procedures. Objective: This study aims to analyze the relationship between invasion patterns, lymphatic invasion, venous invasion, and nerve invasion with the degree of differentiation in OSCC patients at RSUPN Dr. Cipto Mangunkusumo. Methods: This descriptive-analytical study utilized OSCC tissue samples stained with H&E and observed under light microscopy. Results: The majority of OSCC cases were found in the tongue (61.5%), with female patients (56.4%) and the age group over 55 years (53.8%). Aggressive invasion patterns (satellite islands, significant lymphatic invasion (++), significant venous invasion (++), and significant neural invasion (++) were significantly associated with poor differentiation (p<0.05). Conclusion: No significant relationship was found between tumor location, gender, and age with OSCC differentiation grade. A relationship was found between invasion patterns, lymphatic invasion, venous invasion, and neural invasion with differentiation grade in OSCC patients. The more aggressive the invasion pattern, the worse the differentiation grade of OSCC. The worse the differentiation grade, the higher the level of lymphatic, venous, and neural invasion in OSCC.
